Specification of Letters Patent. 1 Patented Apr, 21, 1914;.

Application filed February 18, 1914. Serial No. 818,471.

T0 at 4.0720121 it 'mfzg concern i Be it known that 1,,Cnnnnns P. liloLunar, a citizen of the United States, and resident (it @hicago, countyof Cook, and State of Illinois, have invented certain new and usefulImprovements in Plumbing-Fittings, of which the following is aspecification, and which are illustrated. in the accompanying drawings,forming a part thereof.

The invention relates to plumbingand more particularlyto a fittingadapted to be interposed in an inclined" drain at any one of a pluralityof different positions and to provide an inlet opening to such drain atthe same elevation in each of said positions.

In buildings having solid fioors, as those constructed from reinforcedconcrete, plumb ing fixtures which are so constructed as to dischargethrough the wall'are desirably em ployed. When a plurality of suchfixtures, as a row of toiletclosets-are provided, these preferably alldischarge into a common drain. To provide suitable drainage the drainpipe must be inclined, Whereas the toilet fixtures are preferably alllocated at the same level. Heretofore the connection of such fixtures toa common inclined drain has required the use of a fitting of differentform in connection with each fixture.

The present invention accordingly contemplates a fitting which may bemodified to provide an inlet opening at a predetermined levelirrespective of the level of the drain pipe at the particular locationwhere the.

connection is to be made.

The ob ect of the 1nvent1on is to facilitate the connection of so calledwall closets and other forms of. toilets which discharge through thewail at the rear to a common drain. 4

In the accompanying drawings higure 1 is a front elevation showing aninclined drain equipped with a plurality of fittings of the formprovided by the invention, the toilet closets to be connected with suchfittings being shown in dotted lines and a detail of the floor of thebuilding being shown in section; Fig. 2 is a detail front elevation ofthe fitting; Fig. 3 is a detail sectional view taken on the line 33 of1; Fig. 1- is a plan view showing a form of fitting which may he einpled for the connection of two oppositely facing toilets to a common drainlocated in the intervening wall space, andFig. 5 is a detail sectionalview taken on the line 5 5 of Fig. 4.

The "fitting illustrated in the drawings is more particularly intendedfor use in connection With the installation 'of Wrought iron drainagesystems.

When so used, a drain 24, which is preferably common to a plurality-oftoilet closets, as 10, 11 and 12 is formed by the connection of an equalnumber of fittings, generally designated 13, andintervening sections, as14. and 15, of wrought iron pipe to separate the said fittings inaccordance with the spacing of the closets, 1

Each of the fittings 13 conveniently comprises a substantiallycylindrical body ortion 16 having internally threadedhubs 17, 18 at itsopposite ends. Intermediate. the ends of thecylindricalbody'portipn 16and extending laterally outward therefrom .is a

hollow extension 19, the chamber, as 20, of which forms a well which isin communiation with the bore of the cylindrical body portion 16.Preferably the extension 19 has a horizontal flbor 21 and an outwardlyand upwardly inclined top wall 22. -Most desirablythe floor 21 of theextension 19,, is on a level withthe bottom wall of the c'ylindricalbody portionlfi of the fitting and the top wall'of the extension extendsupwardly from the level of thetop wall of the body portion 16. By thismeans, the front wall,

as 23 of the extension is of a greater height than Width and extendsfrom substantially the level of the under side of the cylindrical bodyof the fitting to an elevation considerably above that of 'the upperside of the body portion of the fitting. .In the original constructionof the fitting the front wall 23 of the extension 19 is desirablyclosed. r

When a plurality of the fittings, 13, are

to be employed for the connection of a,

plurality of closets, as 10, 11 and'1-2, to a common drain 24, the frontwall 23, of the extension 19 of each fitting is drilled to provide anopening 25 therein for the I .connection of the closet to the fitting ata fixed distance from the floor, as 26. As the pitch of the drain 24serves to locate the Sev? oral fittings 13 at different elevations, theopening 25 in the front wall 23 of the several fittings will be locatedat different places, the said opening in the fittingwhich 4O pitch orinclination of the common 'drain op'ening 52S bvbolts, as A more subislocated in a higher part of the drain being positioned lower down uponthe fitting than are the said openings of the fittings which are locatedat a lower part of the drain. The toilet closets, as 10, 11 and 12 maybe connected with the respective fittings 13 in any convenient manner,as for example in the manner illustrated inFig. 3. In this figure therear wall of one ofthe closets, as 10, is represented at 27, thedischarge opening in said wall. being shownat 28. In this instance thecloset 10 is located against an upright wall or panel represented bydotted lines at- 29 and the fitting 13 is located in rear of this panel.The frontwall 23 of the lateral extension 19 of the fitting have beendrilled at. the proper elevation to provide an opening 25 therein whichis upon thesame lcvelas the discharge opening 28 in the rear .wall ofthe closet 10, a threaded nipple 30 is screwed into the opening 25 andextends through the panel 29. A flanged collar 31 is then screwed uponthe front, end of 'the nipple 30 and secured against the rear wall ofthe closet 10 about the discharge ,stantial supportfor the closet may beobt'ainiagt by mounting a collar 33 upon the nipple 30 between the frontwall 23 of the littinglt; and theeollar 31. and by the extensaon ot' thebracket arms or braces, as

- 34, fi-ionrthewollar 33 to the rear wall 37 of the closet above thedischarge opening '28 Each of theclosets, as 10. lland 1'2 ma velevation tor connection with the horizonbe sccuredto the correspondingfitting lit in the same manner as is shown for the closet 10, theditterent location of the opening 27) in each fittin serving toperinitof all of the closets to e positioned at-i'the same distance from thefloor 26 notwit'hstandin-"g, the

24. Usually each of" the. fittings 13, will be provided with anopening3-1'iat the upper side o'f'its. cylindrical body portion for theconnectionthercwith of the usual vent, as 36.

'henclosets which are located at the op posite sides of a wall orpartition are to be connected with a common drain, a fitting oi the-formshown in Figs. 4' and 5 will desirably be used. This fitting may takethe general form of a so-called long sweep double 90 degree Y, having acentral cylindricalbody pdrtion, as indicated at 37, and the twooppositely facing lateral branches,

as 38 and 39. The two branches dllrare each pre'l'erably made verticallyflaring ad-- jacent their outer ends (Fig. 5) and in the originalconstruction of the fitting, these branches will preferably lJQ'ClOSQtlat their outer ends. When a plurality of the fittings are to be mountedin an inclined drain (not shown) the closed ends of the latcal branches,38 and 39 of the several fittings will be so drilled as to provideinlet openings, as 40, all of which will be located at the sameelevation. ,By means of the invention fittings of a uniform design willserve for the connection of a plurality of plumbing fixtures, alllocated at the same elevation, with a connnoh drain. 'lhense of afitting of special Form or the. co struction of built. up elbow branchesto ditl'ercnt heights at the several places where tixlurcs are ocated isaccordinglyavoided.

I claim as my invenLion,---

1. A drain l'or closets and the like comprising. in combination. aplurality of inclined pipe sections located in aliinuneut and aplurality of integral fittings each comprising a tubular part interposedbetween and connecting adjacent pipe sections and a vertically extendedlateral receiving chamber communicating with the bore of the saidtubular partand having an upright end wall, the said end walls of all ofthe said fittings being drilled at the same tally directed outlets ofwall closets and the like.

2. A fitting for inclined drains comprising in combination, acylindrical tubular body portion having its opposite ends adapted forconnection with sectionsof the drain pipe and a pair of. oppositelyfacing verti- .call v extended lateral arms each having an end walladapted to be drilled at any one ol? a plurality of different elevationsfor connection with the horizontallv directed outlet of a wall closet.
